ALFRED H. WEISS, OF WILMETTE, ILLINOIS, ASSIGNOR TO KELLOGG SWITGHBOARDAND SUPPLY COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

SWITCHIBOARD-PLUG.

Application filed May 17,

To all whom it may concern:

Be it known that I ALFRED H. WEISS, a citizen of the United tates ofAmerica, and resident of Wilmette, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inSwitchboard-Plugs, of which the following is a specification.

My invention relates to improvements in plugs, and more particularly toswitchboard plugs employed in telephone switchboards for connectionpurposes. 1

The usual form of switchboard plugs is provided with a main bodyportion, which body portion is provided with a protective sleeve ofsuitable insulating material and held against displacement or movementupon the body of the plug by means of a small screw which passes throughthe sleeve and screws into the body of the plug. This form of fasteningnecessitates the machining of parts as to drilling and tapping, thusadding to the cost of manufacture.

It is often necessary to change a damaged plu or to change a damagedswitchboard cor for another, and with the usual method employed thescrew which holds the protective sleeve in place, bein small, is apt tobe lost. The screw is also ard to handle due to its smallness andrequires considerable time to remove and replace the same, therebymaking the repairin of switchboard plugs slow and tedious. apid repairsare essential intelephone switchboard work so as not to tie up any cordplugs for any length of time when makin repairs. YVith the plug of myinvention, a 1 this amount of extra labor and time is eliminated.

An object of my invention is to construct a plug in which means isprovided in the form of a split rin which rests in a roove in theforward en of the body portion of the plug to retain the protectivesleeve in place on the body of the plug, thus doing away with the smallscrew which is almost universally used for holding the protective sleevein place.

Referring now to the accompanying drawing, I illustrate several forms ofmy invention in which like reference characters in Specification ofLetters Patent.

The extension or sleeve of the plug 3 has an opening which extendsthe length of the said sleeve 3 and is of a size to receive the sleeve4:, which sleeve is of'suitable insulating material. A stem 6 of a sizeto pass through the insulating sleeve 4 is provided,

parts, and in the end of the'said stem 6 being threaded to receive theplug tip 5 of the plug, which tip 5 engages the tip contact of thespring jack, and the sleeve 3 of the plug being a apted to engage thesleeve of the spring jack, as is well understood. The stem 6 is providedwith an enlarged portion 8 which is insulated from the body portion 2 bymeans of'an insulated sleeve 9. This enlarged portion 8 of the stem 6 isprovided with a binding screw 10, which screw 10 has screw threadedengagement with a tapped hole in a the said enlarged portion 8. Thebinding screw 10 is adapted to hold the tip conductor of the cord inelectrical contact with the ti stem 6. A ring of insulation 11 is passebetween the sleeve portion 3 and the tip 5 to insulate one from theother. The body portion 2 has its wall partly cut away to form anaperture 12 so that the bmdmg screw 10 .is accessible therethrough.Surrounding the body portion of the plu 1s a protective sleeve 13 ofsuitable 1ns ti/1 11 material, such as fiber or hard rubber, who

is slipped over the body portion 2 of the '0. F. WELDON. MECHANICALINKING APPARATUS. APPLICATION F ILED MAY 26,1921.

Application filed May 26, 1921. Serial No. 472,661.

To all whom it may concern:

Be it known that I, CHARLES F. WELDON, a citizen of the United States,residin at Delavan, in the county of Walworth, S tate of Wisconsin, haveinvented a new and useful Mechanical Inking Apparatus; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention relates to automatic apparatus whereby the ink within thefountain of a printing press will be thoroughly agitated at all timesand equalized in such a manner that it will be uniform in consistency,and uniformly distributed throughout said fountain, thereby insuringadhesion, of the ink to the fountain roller uniformly.

A further object is to provide a transversely disposed shaft, disposedabove the ink fountain, said shaft having longitudinally movable thereona carriage, which carriage is provided with an ink agitator. Also toprovide the carriage with mechanism 00- operating with oppositelyarranged spiral grooves on the shaft, by means of which grooves thecarriage and agitator aremoved longitudinally on the shaft.

A further object is to provide tripping fingers disposedadjacent theends of the transversely disposed shaft and cooperating with mechanismon the carriage for reversing the direction of movement of the carriageand agitator.

A further object is to provide means whereby the agitator will bedifferently positioned during its reciprocation.

With the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawings, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a top plan view of the ink fountain, showingthe inking apparatus applied thereto.

Fig. 2 is a side elevation of the ink fountain showing the ink stirringdevice therein, and the ink stirrer frame in raised position in dottedlines.

Fig. 3 is a sectional view taken on line 33 of Fig. 1.

Fig. 4 is a detail perspective view of the stirrer.

Referring to the drawings,'the numeral 1 designates the fountain of aprinting press in which fountain is rotatably mounted a fountain roller2, in such a manner that as it revolves ink from within the fountainwill be taken up thereon and transmitted to the printing mechanism inthe usual manner. It has been found that ink within the fountain is notequally distributed and of uni form consistency, therefore toovercomethis objection a stirrer 3 is provided, which stirrer isslidably mounted on a carriage 4 which moves longitudinally on a feedscrew 5 which is rotatably mounted in bearings 6 of the pivoted frame 7.Feed screw 5 is provided with a bevel gear 7, which gear meshes with abevel gear 8 operated in any suitable manner from the main drivemechanism from the printing press in such a manner as to constantlyrotate in the direction of the arrow a. The carriage f has mounted inbearings 9 a shaft 10, which shaft is preferably in parallel relationwith the feed screw 5 and is adapted to be rocked as the carriageapproaches the ends of the feed screw for actuating mechanism which willreverse the direction of movement of the carriage and consequentlyreverse the stirring action of the stirrer 8. The shaft 10 at one endthereof is provided with an arm 11 having alug'lQ with which lug thefinger 13 located adjacent one end of the feed shaft 5 engages when thecarriage reaches that end of the feed screw 5. When the finger 13engages the lug 12 the shaft 10 is rocked in its bearings until the feedscrew engaging finger 14: is forced into the feed groove 15 as shown inFig. 1, and as the feed screw 5 rotates in the direction of the arrow(4, the carriage 4; will move in the direction of the arrow 5. When thefinger 14 is in engagement with the feed groove 15, said finger is heldin engagement with said groove by means of the spring 16 whichcooperates with the pivoted bar 17, which is pivoted as at 18 to a disk19 carried by the shaft 10 and slidably mounted in a pivoted bearingcollar 20 pivoted to the side of the carriage as at 21. The holdingaction is accomplished by the pivotal point 18 passing between thecenter of the shaft 10 and the pivotal point 21 untii the disk 19 islimiter in its rotation by engagement of the linger 14 with the feedgroove "When the arriage reaches the other side of the feed screw 5 thetripping finger which is carried by the shaft 5 will move intoengagement with the lug carried by the arm 52 iwhich is secured to theshaft and force said arin 91 i upwardly thereby rocking the sl 1; 10 andmoving the groove engaging v er into engagement with the feed 'roove 26,which feed groove will as the reed screw 5 revoive 1e carriage to bereversed in its operation and movedto the othe end of the fountain 1.The above is a co nuous one and it will be r 3 r re fountain 1 r the inktherein stantl tirred hence the ink will be 'maintained at a uniformconsistency and prop eriy fed on the fountain roller 2; feed 2:; is inengagement with the feed groove 26, tile spring 16 and the shaft 17 arein the positions shown in Fig. 2, thereby main ning; the finger in closeengagement with 0 ing displacement of the saline.

The stirrer 3 is provided with reanvardly and outwardly extending curveddeflecting; members 527, which members during the reciprocation of thestirrer deflect in the direction. of the fountain roller 2 so that itwill readiiy feed unto said roller immediately following the stirringoperation. Extending rearwardly s "er 3 is an integral arm 28, the rearend of which is provided with slot 29 through which slot a screw 30extends. it willbe seen that'by providing slot 29 that the stirrer 3 maybe moved toward and away from the fountain roller 2. To accomplish theabove bar is slidably' mounted cause t to the oth r in such in bearings32 in the upper side of the carriage i, the forward end of which ispivotaliy connected as 33 to i 3 awn 3 ot the lever 35. Lever 35 has itspivot-ally connected as at 36 to the stirrer and its arm 37 pivotallycon nected at 38 to the arm 39 carried by the s1 tit 10. it will be seenthat as the di-- rection of movement of the carriage t is changed at theends of the strokes that the stirrer will be positioned differently inas relation to the fountain roller 2 thereby positioning the stirrer sothatduring its ll move from one 1* ll be con the ink -iroin the 7 an 7eo-1. 21s

reciprocation it will not move throughthe same part of the ink fountain1 but will be differently positioned, thereby insuring uniform andthorough stirring of the ink throughout the fountain.

Frorn the above it will be seen that air ink equalizer is provided whichis simple in construction and one wherein the parts are reduced to aminimum The carriage iis provided with a plate 40 having a notch 41therein in which notch the fiangedQ of the pivoted frame is received.Plate d0 forms means for guiding the carriage l in its reciprocation. vi

The invention having beenset forthwhat is claimed as new and useful is Il.
